During the study, Dr Barbara Binder, of the Medical University of Graz, Austria, and colleagues studied 46 consecutive patients (32 women and 14 men) with superficial vein thrombosis between November 2006 and June 2007.

Valves in the vein close like gates if blood tries to run in the wrong direction, but if these valves fail to work properly, blood is forced to flow back down the leg causing superficial veins under the skin to bulge.

These new methods of resolving venous hypertension in the superficial veins of the lower extremities are safe and offer better patient outcomes with significantly less patient inconvenience than prior surgical remedies.
